Subject [jira] [Created] (SPARK-22934) Make optional clauses order insensitive for CREATE TABLE SQL statement
Date Mon, 01 Jan 2018 07:03:00 GMT
Xiao Li created SPARK-22934:
-------------------------------

             Summary: Make optional clauses order insensitive for CREATE TABLE SQL statement
                 Key: SPARK-22934
                 URL: https://issues.apache.org/jira/browse/SPARK-22934
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.1
            Reporter: Xiao Li
            Assignee: Xiao Li


Each time, when I write a complex Create Table statement, I have to open the .g4 file to find
the EXACT order of clauses in CREATE TABLE statement. When the order is not right, I will
get A strange confusing error message generated from ALTR4. 
{noformat}
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] [db_name.]table_name
    [(col_name1 col_type1 [COMMENT col_comment1], ...)]
    USING datasource
    [OPTIONS (key1=val1, key2=val2, ...)]
    [PARTITIONED BY (col_name1, col_name2, ...)]
    [CLUSTERED BY (col_name3, col_name4, ...) INTO num_buckets BUCKETS]
    [LOCATION path]
    [COMMENT table_comment]
    [TBLPROPERTIES (key1=val1, key2=val2, ...)]
    [AS select_statement]
{noformat}

The proposal is to make the following clauses order insensitive. 
{noformat}
    [OPTIONS (key1=val1, key2=val2, ...)]
    [PARTITIONED BY (col_name1, col_name2, ...)]
    [CLUSTERED BY (col_name3, col_name4, ...) INTO num_buckets BUCKETS]
    [LOCATION path]
    [COMMENT table_comment]
    [TBLPROPERTIES (key1=val1, key2=val2, ...)]
{noformat}

The same idea is also applicable to Create Hive Table. 
{noformat}
CREATE [EXTERNAL] TABLE [IF NOT EXISTS] [db_name.]table_name
    [(col_name1[:] col_type1 [COMMENT col_comment1], ...)]
    [COMMENT table_comment]
    [PARTITIONED BY (col_name2[:] col_type2 [COMMENT col_comment2], ...)]
    [ROW FORMAT row_format]
    [STORED AS file_format]
    [LOCATION path]
    [TBLPROPERTIES (key1=val1, key2=val2, ...)]
    [AS select_statement]
{noformat}

The proposal is to make the following clauses order insensitive. 
{noformat}
    [COMMENT table_comment]
    [PARTITIONED BY (col_name2[:] col_type2 [COMMENT col_comment2], ...)]
    [ROW FORMAT row_format]
    [STORED AS file_format]
    [LOCATION path]
    [TBLPROPERTIES (key1=val1, key2=val2, ...)]
{noformat}
